Detailed Description
[PREVIEW] [Medical] Interactive distance measuring tool for SoOrthoSlice.
This node displays an interactive distance measuring tool on top of an SoOrthoSlice. The user can click and drag to display a line and the physical distance between the clicked point and the current cursor position.
This node is only intended to be used in a "2D" viewing environment using an SoOrthographicCamera, for example viewing a single slice of a medical volume.
This node requires that the application handle mouse press, release and move events. Mouse move events must be forwarded to the node using the manageMouseMove method. See example examples/source/Medical/Analysis/medicalRuler.

| static void Ruler::exitClass | ( | ) | [static] |
Finish using class (called automatically by InventorMedical::finish()).
Reimplemented from SoSeparator.
| static SoType Ruler::getClassTypeId | ( | ) | [static] |
Returns the type identifier for this class.
Reimplemented from SoSeparator.
| SoFont* Ruler::getFontNode | ( | ) | const |
Returns the internal font node.
The application can use this to modify the appearance of the text.
| virtual SoType Ruler::getTypeId | ( | ) | const [virtual] |
Returns the type identifier for this specific instance.
Reimplemented from SoSeparator.
| static void Ruler::initClass | ( | ) | [static] |
Initialize class (called automatically by InventorMedical::init()).
Reimplemented from SoSeparator.
| bool Ruler::manageMouseMove | ( | bool | firstClick, | |

The application should call this method with 'true' on the mouse down event that begins a measure operation, then call this method with 'false' on each mouse move event during the measure operation.
See the medicalRuler example program for more details.
